改良低分子肝素注射方法对择期冠状动脉介入患者皮下出血的影响

目的探讨低分子肝素的注射部位、注射方法对择期冠状动脉介入患者皮下出血的影响。方法将250例行择期经皮冠状动脉介入术治疗的稳定型心绞痛患者,采用随机数字表法分为对照组和实验组,各125例。对照组采用传统注射法,实验组采用改良注射法,比较分析两组患者注射低分子肝素后致皮下出血的情况。结果实验组皮下出血发生率低于对照组,差异具有统计学意义(P0.01)。结论改良法皮下注射低分子肝素可有效减少择期冠状动脉介入患者皮下出血的发生率,有利于全面提高医疗护理质量。

Effects of the modified injection method of Low Molecular Weight Heparin on subcutaneous hemorrhage in patients after elective coronary intervention therapy

Objective To explore the injection methods and injection sites of Low Molecular Weight Heparin （LMWH） on subcutaneous hemorrhage in patients after elective coronary intervention therapy. Methods A total of 250 patients with stable angina, who had received percutaneous coronary intervention therapy were randomly divided into the control group（ n = 125 ） and the experimental group（ n = 125 ）. The traditional injection method of LMWH was used in the control group, and the modified injection method of LMWH was used in the experimental group. The subcutaneous hemorrhage caused by LMWH was compared between the two groups. Result The incidence of subcutaneous hemorrbage in the experimental group was significantly lower than that of control group （ P 〈 0.01 ）. Conclusion The modified subcutaneous injection method can significantly reduce the incidence of subcutaneous hemorrhage and improve the quality of medical care.
